Hi all, I was having this problem also, and after some debugging I was able to trace the problem to a function in the file onmainwindow.cpp at the x2goclient package. Enabling the debug on the client I saw at the step of creating the xinerama.conf file inside $HOME/.x2go/xxxxxx/ directory the following: x2go-DEBUG-../sshmasterconnection.cpp:1469> executing remote: "sh -c 'echo X2GODATABEGIN:38317d7e-972d-417f-9745-ef9cb09d7e35; PATH=/usr/local/bin:/usr/bin:/bin export DISPLAY=:50;printf '1600 0 1600 900\\n0 0 1600 900' > $HOME/.x2go/C-fpedemonte-50-1426195616_stDXFCE_dp24/xinerama.conf; echo X2GODATAEND:38317d7e-972d-417f-9745-ef9cb09d7e35;'" As you can see, the "\n" is not escaped correctly. What I did was to modify the following line of code inside onmainwindow.cpp line 10212 QString cmd="export DISPLAY=:"+resumingSession.display+";printf '"+screens.join("\\\\n")+"' > $HOME/.x2go/C-"+ resumingSession.sessionId+"/xinerama.conf"; To: QString cmd="export DISPLAY=:"+resumingSession.display+";printf \""+screens.join("\\n")+"\" > $HOME/.x2go/C-"+ resumingSession.sessionId+"/xinerama.conf"; After this modification, xinerama is working again. Take note that I also replaced the single quote by double quote and escaped them. Without this modification the printf command was failing to create the xinerama.conf file. Thanks for this excelent piece of software Best Regards Fernando D.
